About this network

CT-Guangzhou-IDC is China Telecom's Guangzhou internet data centre network, registered to CHINANET Guangdong province network (APNIC). It is the IDC ASN, not China Telecom's Guangdong broadband network.

What it's used for

• Hosting and public cloud. As of 2026-11-10 it announces 257,024 IPv4 addresses (94 collapsed prefixes) plus 31 IPv6 prefixes. Most of the space is registered to cloud and IDC tenants:
• UCLOUD-NET, UCloud: 19.1%
• HWCSNET, Huawei Public Cloud Service: 15.3%
• JDCOM, JD.com: 6.4%
• CloudVsp: 4.8%
• BJKSCNET, Kingsoft Cloud: 4.8%
• YUNIFY-NET, QingCloud: 2.9%
• ofidc, Guangdong Aofei Data: 2.5%
• CHINA-21VIANET: 2.1%
• VOLCANO-ENGINE: 1.6%
• smaller blocks: VClouD, Baidu, Chinac and others
• 24.1% is China Telecom's own CHINANET-GD space, originated from this IDC ASN.

Notable

• An earlier version of this card classified the network as residential. It read the tenant netnames as a mix of eyeball and enterprise users. They are cloud providers renting IDC space, so the network is now classified as hosting.
• The only block that looks like eyeball space is GZPRBNET, GuangZhou Radio & Television network (124.40.128.0/18, 6.4%).
